Copper Hydroxide Ethanedisulfonate: A Cationic Inorganic Layered Material for High‐Capacity Anion Exchange

“…These structural characteristics likely allow the formation of a cationic structure, for a range of potential applications similar to LDHs such as anion exchange, catalysis and drug delivery. [7] In addition to PXRD, Fourier-transform infrared spectroscopy (FTIR) also confirms the presence of sulfonate ligands [1200m, 1070m (cm À1 ): RSO 3 À stretch, Figure S3]. Thermogravimetric analysis-mass spectroscopy (TGA-MS) indicates SLUG-26 is thermally stable to ca.…”

“…[6] The typical approach to trap these intrinsically anionic pollutants remains ion exchange resins, though these organic polymers possess limited thermal and chemical stability and thus longevity. [7] Cationic inorganic layered materials are 2-D extended architectures where the positively charged layers are held together electrostatically by charge-balancing anions. One typical and widely studied example is the layered double hydroxides (LDHs) with general formula [ ).…”

Fabrication, characterization and evaluation of mesoporous activated carbons from agricultural waste: Jerusalem artichoke stalk as an example

“…As shown in Fig. S6(a) and Table 1, high total carbon yields of 35.5%-44.0% could be obtained from run numbers 5,7,8,13, and the corresponding ZnCl 2 dosage are all at low level. But the yields sharply decrease to the range of 33% and 35%, as the ratio increase from 1 to 4 (corresponding groups 12, 2, 15, and 1).…”

“…A three factor-tree coded level BBD was used to obtain optimum conditions for the critical factors [13]. The actual values of the independent variables (X i ) were coded to x i according to following equation:…”

Chromatography of Non-Steroidal Anti-Inflammatory Drugs: New Achievements

“…The data indicated that the concentration of chlorine exerts the highest influence on the decomposition and the decomposition process started by the aromatic substitution of one or two hydrogens by chlorine and/or bromide. The method was successfully applied for the determination of target compounds in drinking water and wastewater samples [23].…”
